The ICS502 LOCO™ is the most cost effective way to generate a high quality, high frequency clock output and a reference from a low frequency crystal or clock input. The name LOCO stands for LOw Cost Oscillator, as it is esigned to replace crystal oscillators in most electronic systems. Using Phase-Locked-Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive crystal to produce output clocks up to 160 MHz.
Stored in the chip's ROM is the ability to generate 6 different multiplication factors, allowing one chip to output many common frequencies (see page 2).
